Lucia

Lucia, also known as Χ (Chi), is a secretary demon created by Arius. She later defected from him and became a member of Vie de Marli's Clan, adopted by Matier as her daughter and apprentice to be trained as a Devil Hunter. She later worked alongside Dante to defeat both Arius and Argosax. She appears in Devil May Cry 2 as one of the main protagonists and a playable character.

Personality
Lucia takes her job as a Devil Hunter seriously, being frank and to the point when speaking. However, she possess a soft and kinder side, as seen as she shows kindness and caring for Matier on multiple occasions, (despite later learning they're not related by blood) and Dante, who she placed her trust into with no objection of any sort. Lucia is also very selfless, and upon finding out she was a demon created by Arius, she asks Dante to kill her to prevent her from going insane and killing innocent people, as Arius said she would. She is also shown openly worrying for Dante's safety when he claims he intends to enter the portal.

She does possess a humorous side. Upon finding out that Dante's coin is actually a two-headed coin, she grins while giggling and fondly refers to him as "That macho ...".

Appearance
Tall and lithe, Lucia appears as an attractive woman with tan skin. She wears her bright red hair in a braid over her left shoulder. The most notable pieces of her wardrobe are her short, white cape and her exposed midriff. She also has deep emerald green eyes, which help accent both her tanned skin and bright red hair. She wears brown leather gloves that have white lining, and various brown leather gear on her outfit: the holsters for her blades, the pouches for her throwing knives, as well as a series of leather clasps to help keep her cape in place. Her red hair, white cape, and grey top/pants are meant to mirror the color scheme of Dante. Her Red hair to go with his red cloak and her white cape/grey clothing meant to go with his silver hair.

Gameplay
When in Lucia's Devil Trigger, equip the Aerial Heart and fly in the air, Press +/+ constantly until you do not have control of Lucia. It can also be used when underwater during missions 6, 7, and 8. She will perform a powerful attack that causes magic orbs made of light to rain down onto targeted enemies. If you keep pressing it fast it will not waste Devil Trigger at all, but it will eventually stop.

Devil May Cry 2
Lucia lures Dante to her island so that Matier, her mother, may ask him to help them to defeat Arius, a sorcerer/millionaire who plots to merge with Argosax (a powerful demon) and take over the world. Matier asks Dante to help Lucia to find the remaining parts of the Arcanas, the four ancient, sacred relics used to seal Argosax away from this world and the artifacts which Arius is so desires for. Dante accepts, and he and Lucia start their quests separately.

Much later, Lucia meets Arius. Arius reveals that she is actually a mannequin, like the Secretaries, and was created by him. He says that she was a "defect" and so was about to be disposed of when Matier found her. He also tells her that a mark on her left shoulder - "X" (Chi) (pronounced "Kai") - is actually her real name. Then he demands that Lucia gives him the Arcanas that she have already found. After she angrily rejects, he says that "the world is already warped" and that "everything that belongs to the devils will eventually revert to its original form", including Lucia, and leaves her, uncertain about her own future.

Despite this, Lucia continues her mission to find all the remaining parts of the Arcanas. When she gathers them all, she gives Arcana to Dante, asking him to bring them to Matier for her. After that, she leaves to finish Arius by herself, but is unsuccessful and gets captured. Later Dante comes to rescue her, and gives out all the Arcanas despite Lucia's protests. After Arius and Dante fight, the sorcerer uses his hostage to pull them both out of the building. However, Dante transforms into a devil and they fly to safety. Lucia then asks him why he saved her to which he replies that "every hero has a weakness". There she also meets with Matier, who confirms that they are not tied by blood, but also says that their ties are bound by history and experience, which are much deeper then blood. Then after Lucia thanked her mother for the truth and love, she goes after Dante.

Lucia and Dante manage to enter the Uroboros Corporation's skyscraper building again, just to see that the sun has completely eclipsed and that the ritual cannot be stopped. After something in it goes wrong, it is revealed that Dante had switched the Medaglia coin with his own. Dante attacks the distracted Arius and defeats him. Watching this seemingly end, Lucia attacks Dante and asks him to kill her. She tells him about her doubts and then asks him to kill her again. Before Dante can decide anything, the door to the Demon World opens, even though the ritual was incomplete. Lucia says that she will go because she is "expendable", to which Dante suggests to leave it to fate. After heads fall once again, he takes a motorcycle and enters the Demon World. After Dante leaves, Arius, now completely turned into a vengeful undead monster, rises out of hellfire from the ruins of the building that had been the giant, Nefasturris, but Lucia puts this twisted abomination to rest. Shortly after, she is seen near the closed portal between the four separate Uroboros skyscrapers, waiting for Dante. Matier is also here, and comforts her, saying that should not worry as "everything is just as it was with Sparda". Lucia then gets the coin Dante gave to her and reveals that both sides are heads.

Much later, Lucia is shown waiting in Dante’s shop, flipping his coin continuously. She then hears a motorcycle outside the shop and goes out running. However, whether this is Dante or not is never revealed.
